1st Dec Full Disk

Post by minhlead »

I think I improved a bit on sharpness by increasing the gain and lower exposure time. Was 1.8ms and have quite a lot of blurriness across the disk. Now I am exposing for about 0.4 ms and the result look much sharper.

That shorter exposure is much better.

Yeah. The last few days I did not turn on the cooler. Thought I do not need it since it's winter and ambient temperature is around 20*C. But apparently my Quark still requires the cooler to be onband.

Yeap. Did not expect such a big improvement. I have never ever thought 2ms exposure is still too long. I used to shoot planetary and anything under 5ms is more than enough to beat the seeing. Apparently solar need much shorter exposure time.
